That's two steps, right? First you make a partition on the "disk" qemu
provides, then you put a filesystem on the partition? Or did you put a
filesystem on the raw device?

Does mount know to use Minux3 with this command line?

Having been burned a few times by the fact that qemu provides disk
images which then (normally) get partitions, I'm not sure you aren't
having the same problem.
None of which justifies the OOPS, of course, nice kernels don't go down.
